“We ought, therefore, in all that we learn, to gather brief and dependable abstracts to be stored in the little chest of the memory, so that later on, when need arises, we can derive everything else from them. These one must often turn over in the mind and regurgitate from the stomach of one’s memory to taste them, lest by long inattention to them, they disappear. I charge you, then, my student, not to rejoice a great deal because you may have read many things, but because you have been able to retain them. Otherwise there is no profit in having read or understood much. And for this reason I call to mind again what I said earlier: those who devote themselves to study require both aptitude and memory.” Hugh of St. Victor, Didascalicon, Book 3, Chapter 11. [Emphasis added]
For this reason, the word, rumination, has the various meanings.
